to know that your president is going to survive four years. >> remember carol when we talked about john mccain's age. that came up. it was a realistic concern for people. ronald reagan, obviously. i think this is going to hold chris christie back if he has further applebitions to be president. i think we know he does. but it is out of line for someone like that doctor to diagnose, we have a lot of radio shows that diagnose people based on the way they look. it's irresponsible and doctors that know better wouldn't do that kind of thing. chris christie, again, i think he's a role model and could do a lot. he doesn't have to. but he could show people how hard he is trying to lose weight. i also understand how much of a struggle it is, it is difficult emotionally and physically. >> he was elected governor. would you have thought he would have been elected? >> it's fine to be governor, but that's different -- you are running against a president who was in office, who used to come out of the water like bo derek in hawaii. if chris christie doesn't fix it, it will be a problem. >> he's the governor.
